Via a sync cord to the flash

Right, but when it is connected to the camera how is it connected?

Actually, none of it connects to the camera - there is a lead to connects to the flash but that's not connected in this picture.

The camera shutter is held open for a few seconds at a small-enough aperture and a dark enough room that it does not register any significant image except when the flash fires.

Cool stuff. So what part connects to your camera?
